Zebrafish Embryo, from tailbud to 16-hour stage, stained with 100 micromolar Bodipy-Ceramide. Bodipy-Ceramide permeates the enveloping layer epithelium of the embryo, accumulating in the interstitial ...

Differentiated rat neural stem cells stained for β III-Tubulin (in green) to reveal neurons, GFAP (in red) to reveal glial cells, and DAPI (in blue) to label nuclei.

Zebrafish Notogenesis and Early Neurulation. Mediolateral intercalation produces convergent-extension of the notochordal rudiment. Cells within the center of the notochord elongate and are incorporate...

A 4D visualization of zebrafish somitogenesis and neural keel formation. The Quicktime movie shows progressively dorsal optical sections in a segmenting embryo. Note the midline alignment of neuroepit...

This group represents a serial series of sections. At the level of this section the funnel shaped oral region is now reduced to a narrow cytopharyngeal tube extending toward the aboral region of the c...

Tetrahymena cells that are not forming a digestive vacuole often have a tube-like extension of the cytopharyngeal membrane attached to the deep fiber that extends several microns into the cytoplasm. T...
